setNumThreads method if using the object-based API, and the
n_threads parameter in the hnsw_* function
API. For finer control, a setGrainSize and
grain_size option is also available in the object and
function interface respectively. Thank you to Dmitriy Selivanov for a lot of
the work on this.verbose = TRUE now has incurs substantially
less computational overhead associated with calculating the progress
bar. Thank you to Samuel
Granjeaud for spotting the problem and coming up with various
solutions.progress. By default this is set to
"bar" and will show the progress bar when
verbose = TRUE. If you want a more terse output, set
progress = NULL. progress = NULL will
eventually be the default setting: for now, verbose = TRUE
will get you the progress bar by default for backwards
compatibility.markDeleted, that will remove an object
from being retrieved from the index.resizeIndex, that allows the index to be
increased without having to save and reload the index.size is available for the index objects
and reports the number of items added to the index.hnsw_search would stop if the number of
rows in the input matrix was smaller than k. This check has
been removed. Note that the correct behavior is to ensure that
k is smaller than or equal to index$size()
where index is the index you are searching. Because the
size() method is new to this version, to preserve
compatibility with old indexes, this check hasn’t been added to
hnsw_search. If this matters to you, manually compare
index$size() with k before running
hnsw_search. An error will be thrown if k
neighbors can’t be found in the index. Thank you to Yuxing Liao for spotting this and
the pull request to remove the check.Initial release.
